Art museums are institutions or buildings where objects of aesthetic value are preserved and displayed. Functions of the art museum include acquiring, conserving, and exhibiting works of art; providing art education for the general public; and conducting art historical research. Art museums may be classified into two major categories: public museums, administered directly by the national or local government; and private museums, under the authority of a board of trustees, which is composed of private citizens and a director chosen by the board. In addition, art museums are of two basic types: the general museum, which presents a broad range of works from early times to the present, and the specialized museum or gallery, in which the collection is restricted to the works of a single artist or is concentrated on a particular type of art, historical period, or geographical area. The personnel of large museums generally includes a professional staff composed of administrators, curators, conservators, a registrar, librarian, and specialists in education. In the past the art museum functioned principally as a storehouse of objects, but in recent years its social and educational role has been greatly expanded. Increasingly, large metropolitan art museums seek to serve the interests of the national or local community in which they are located. In addition to exhibiting objects in their own collections, many museums develop special temporary or "traveling" exhibitions that are later displayed in other institutions. They also organize guided tours of the collections, publish catalogs and bulletins, sponsor lectures, and provide educational facilities--libraries, study galleries, and art classes--for students. Historical Development The word museum is derived from the ancient Greek name for the temple of the Muses, the patron goddesses of the arts. The term was originally used to refer to institutions of advanced learning. It did not assume its present meaning until the Renaissance, when the first great collections of art were formed in Italy, the result of a burgeoning desire for knowledge of the past, especially classical antiquity. The impulse to collect art soon passed to princes, nobles, and clergy throughout Europe. Art collectors began not only to acquire ancient Greek and Roman art objects and relics of the Middle Ages but also to patronize works by contemporary artists. These collections became, in some cases, the foundations of today's most famous museums. For example, the powerful \TMedici\t family of Florence amassed a vast collection of ancient and modern works of art that formed the basis of, among other museum collections, the Uffizi Gallery, one of the richest repositories of art in the world. Hundreds of private collections were formed throughout Europe in the 17th and 18th centuries. However, as in the Renaissance period, almost all collections were private, and public access to them was extremely limited. A notable exception was the collection of Elias Ashmole in England, which became (1683) the Ashmolean Museum, Oxford, the first university museum. Seventy years later, the collection of Sir Hans Sloane was bequeathed to the nation, resulting in the establishment of the first museum organized as a public institution, the British Museum. Beginning in the late 18th century, a number of public art museums were founded, formed principally of royal or princely collections that either came under public control as the result of political changes or were voluntarily donated to the nation. The principle of public control over art and art collections was firmly established in France during the Revolution, when the royal collection was nationalized (1793) and opened to the public as the Louvre Museum. Inspired by the creation of the Louvre, King Frederick William III of Prussia declared his collection public in 1797, leading to the establishment of the Kaiser Friedrich Museum, Berlin. In 1809 the Brera Picture Gallery, Milan (originally the collection of the Accademia di Belle Arti), was opened to the public. The National Gallery, London, one of the few major European museums not originating from a royal collection, was founded in 1824. In 1852 the Hermitage Museum, Leningrad, containing the tsar's private art collection, was opened to public view on a regular basis. In the second half of the 19th century, a number of specialized museums were created in Europe, such as the Bavarian National Museum (1855), Munich, devoted almost exclusively to the fine and applied arts of South Germany, and the Museum of Ornamental Art, London (1852), renamed the Victoria and Albert Museum in 1899, originally established to display and encourage modern handicrafts. The first museums to be established as public institutions in the United States were the Museum of Fine Arts, Boston (1870), and the Metropolitan Museum of Art, New York City (1872), followed (1879) by the Art Institute of Chicago, which originated as an art school and museum. Since 1900 major trends in art museums have included the attempted reform and expansion of large institutions and the creation of a multitude of specialized museums, many of which are devoted to modern art. In recent years a number of the world's largest museums have attempted to reduce the size and refine the quality of their collections by selling less important works of art and concentrating available funds on acquiring works of greater artistic merit or historical significance. Some have also embarked on vast programs of expansion, such as the National Gallery of Art, Washington, D.C., which opened (1978) a new wing designed by I. M. Pei. Major museums devoted entirely to modern art include the Museum of Modern Art, New York City (1929); the Gallery of the Twentieth Century, West Berlin (1949); and most recently, the Beaubourg, Paris (1977). Also known as the Pompidou Center, it houses not only the National Museum of Modern Art but also an institute devoted to music, acoustics, and film, in addition to video and slide archives. Two other types of museums are distinct creations of the 20th century: the open-air museum, or sculpture garden, and the children's museum. Major Art Museums of the World Austria.
